+# Tooling support
+
+Tooling for in-browser execution is often of uneven quality. WebAssembly aims at
+making it possible to support truly great tooling by exposing
+[low-level capabilities][] instead of prescribing which tooling should be
+built. This enables:
+* Porting of existing and familiar tooling to WebAssembly;
+* Building new tooling that's particularly well suited to WebAssembly.
+
+  [low-level capabilities]: https://extensiblewebmanifesto.org
+
+WebAssembly development should be self-hosting, and not just as a cute hack but
+as enjoyable platform that developers actively seek out because the tools they
+want and need *just work*. Developers have high expectations, and meeting these
+expectations on tooling means WebAssembly has the features required to build
+rich applications for non-developers.
+
+The tooling we expect to support includes:
+* Editors:
+  - Editors such as vim and emacs should *just work*.
+* Compilers and language virtual machines:
+  - Compilers for languages which can target WebAssembly (C/C++, Rust, Go, C#)
+    should be able to run in WebAssembly themselves, emit a WebAssembly module
+    that can then be executed.
+  - Virtual machines for languages such as bash, Python, Ruby should work.
+  - Virtual machines which use a just-in-time compiler (JavaScript VMs, luajit,
+    pypy) should be able to support a new just-in-time backend for WebAssembly.
+* Debuggers:
+  - Basic browser integration can be done through source map support.
+  - Full integration for languages like C++ require more standardization effort
+    on debugging information format as well as permissions for interrupting
+    programs, inspecting their state, modifying their state.
+  - Debug information is better delivered on-demand instead of built-in to a
+    WebAssembly module.
+* Sanitizers for non-memory-safe languages: asan, tsan, msan, ubsan.
+* Opt-in security enhancements for developers' own code: developers targeting
+  WebAssembly may want their own code to be sandboxed further than what
+  WebAssembly implementations require to protect users.
+* Profilers:
+  - Sample-based.
+  - Instrumentation-based.
